ATOP-DAILY(1)               General Commands Manual              ATOP-DAILY(1)

NAME
       atop-daily - daily maintenance of pcp-atop PCP archives

SYNOPSIS
       $PCP_BINADM_DIR/atop-daily [--compress-only] [--help] [LOGPATH]

DESCRIPTION
       atop-daily performs daily maintenance of pcp-atop(1) PCP archives.  It
       is normally called from systemd(1) via the atop-daily.timer unit, or
       automatically by pcp-atop(1) at startup.

       When run without options, atop-daily creates the archive directory if
       absent, compresses prior-day archives using xz(1) for metadata and
       zstd(1) for data volumes, and culls archives older than LOGGENERATIONS
       days (default 28).

       Compression is non-blocking: files are atomically renamed then
       compressed by background processes so the caller and pcp-atop(1) can
       proceed immediately.

OPTIONS
       --compress-only
              Compress prior-day archives only; do not cull old archives.
              This mode is used when called from pcp-atop(1) itself at
              startup.

       --help Display a usage message and exit.

CONFIGURATION
       The following environment variables may be set in the pcp-atop(1)
       sysconfig file (/etc/sysconfig/atop or /etc/default/atop):

       LOGPATH
              Archive directory.  Default: /var/log/atop.  May also be
              specified as a command line argument.

       LOGGENERATIONS
              Number of days of archives to retain.  Default: 28.  A value of
              0 disables culling.

FILES
       /var/log/atop
              Default directory for pcp-atop(1) archive files.
